To find one-third of three-fourths of a pizza, you can multiply the fractions together.
First, calculate three-fourths of a pizza:
\[ \frac{3}{4} \text{ of pizza} \]
Then, find one-third of that result:
\[ \frac{1}{3} \times \frac{3}{4} = \frac{1 \times 3}{3 \times 4} = \frac{3}{12} = \frac{1}{4} \]
So, one-third of three-fourths of a pizza is \(\frac{1}{4}\) of a pizza.
